[E1000-devel] [PATCH 1/1] ixgbe: synchronize link_up and link_speed of a slave interface

[zyjzyj2000]

From: Zhu Yanjun <yanjun....@windriver.com>

According to the suggestions from Rustad, Mark D, to all the slave 
interfaces, the link_speed and link_up should be synchronized since
the time span between link_up and link_speed will make some virtual
NICs not work well, such as a bonding driver in 802.3ad mode.
